AI Technical Summary
The fixed sieve aperture of existing soybean seed screening equipment cannot be flexibly adjusted, resulting in insufficient screening accuracy or low efficiency, and it is also prone to clogging, affecting its service life.
An adjustable aperture soybean seed screening device was designed. By combining a first sieve plate and a second sieve plate, the sieve aperture is adjusted using a drive component. It is also equipped with a vibrator and a distance sensor to automatically monitor the sieve aperture size, ensuring screening efficiency and effectiveness.
It improves screening efficiency and accuracy, reduces clogging, and extends equipment lifespan.
